Yes we're teenagers. We've been married 15 years, ceremony was when we were three.

Privacy is important, have you never kept a diary? Do you film therapy sessions lest your partner not know what you discussed? Shit with the door open? You don't need justification for wanting privacy, you need privacy so when you have a good reason for it nothing looks different.

What if there’s an emergency?

What if there is? Get help, that's an insane fear to live with. If I am unconscious there's nothing to do anyway, the hospital or whatever will find her details in my purse and call. What the fuck am I going to do, sit there watching the dot on the map and calling 000 if it stops moving? You are a lunatic, we have society to take care of us while we're out and about and emergency beacons if you're like camping beyond the black stump or sailing the Pacific.

Why would you want to give third parties access to your locations?

I really think you nailed it and that folks here are either kids or never grew out of the high school mentality. It seems like they conflate trust issues with openness, and that you would only share with your spouse because your spouse doesn't trust you.

My wife has my location. My wife has had my location when I've gone to bachelor parties and done bachelor party activities. I doubt she looked at it. When I came home, I told her about things we did because we take an interest in one another's lives.

It really all comes down to efficiency. She's an hour from home and I need to start cooking dinner soon? I'll go grab the kids now and come home and get going. It just helps plan days and nights.
